Period of small oscillations in the two ...

Period of small oscillations in the two cases shown in figure is `T_(1)` and `T_(2)` respectively . Assume fluid does not have any viscosity , then

A

`T_(1) =T_(2)`

B

`T_(1) lt T_(2)`

C

`T_(1) gt T_(2)`

D

Cannot say anything

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `T_(1)=2pisqrt((m)/(k+rhoAg))` but `T_(2)=2pisqrt((m)/(k))`
Hence , `T_(1) lt T_(2)`
